I suspect that your feeble 120v circuit may have contributed to the demise of the motor on the R4512. Running it on 220v may have prevented the “seizure”.

As for the trunnions….they do both look very, very similar, but that doesn’t mean the motors are the same, and just because they look the same doesn’t necessarily mean that they’re identical. The G0715P definitely adds solid cast wings, a steel t-square fence, and a full enclosure….a little nicer, heavier saw with a better fence. AFAIK, the alignment issues have been rectified on the G0715P….interestingly, many of the R4512 and 21833 models had similar alignment problems, which lends more credibility to the rumors that the trunnions are the same.

If you can get 220v 20 amp service, the 3hp G1023RL is a far more substantial saw than any you’ve mentioned, including the Jet hybrid… $1294 shipped. Look at the pics of those trunnions compared to the hybrid or contractor saws.

Here’s an exploded pictorial of the guts of the G0715P:

Here’s a pictorial of the guts of the Cman 21833, which are the same as those on the R4512:
